FEATH ER-EDGlNG MACHINE.

Specification forming part of Letters Patent No. L141,300, datedSeptember 20, 1864.

To all whom it may concern:

Beitknown that l, LOUIS GODDU, of Braintree, Norfolk county,Massachusetts, now temporarily residing at Montreal, Canada, a subjectofthe Queen of GreatBI-itain,havingmade oath of intention to become acitizen ofthe United States,'have inventedlmprovementsin Feather-EdgingMachines; and I do hereby declare that the following, taken inconnection with the drawings which accompany and form part of thisspecification, is a description ot' my invention sufticient to enablethose skilled in the art to practice it.

My improvement relates principally to the construction ot' machines forleather-edging or chamfering and reducing to an even thickness soles forboots and shoes, the invention consisting, chiefly, in the employment,in connection with feed-rolls and a surface against which the edge ofthe sole is guided, of a pointed instrument, or directing rod or bar,which keeps the edge of the sole up to the guiding-surface; also, in theemployment, in connection with the feed-n heels, of dinkingpoints uponthelowerfeed-wheel, for the purpose of (linking or spacing the peg-holesin the bottom of a sole; also, in so arranging the chamfering-knife, therolls, and the directingrod that while the knife, keeps a iXed relationto the lower feed-roll and the plate upon which the sole rests theguide-rod and upper roll yield to the inequalities of thickness ofthesole also, in so constructing the machineth at the knile and nprer rollare raised and lowered and lixed'in position together, to adapt themachine to stock of varying thickness; also, in giving the surface uponwhich the sole rests and the bearing-surface of the feed-rolls aninclination with respect to the horizontallyarranged cutting-edge of theskiving-knile.

In the drawings, Figure 1 represents a side elevation ot a machineembodying my invention. Fig. 2 is a front View, and Fig. 3 a sideelevation, of the head of the machine, these views being full size,while Fig. l is one-half s'ze of the machine.

a denotes theframe; b,a horizontal drivingshaft, carrying on its frontend the lower feedwheel, c. This shaft has a gear, d, which meshes intoa similar gear, e, on another shaft, f, which carries the upper feedroll, g. The lower shaft rotates in stationary bearings, while the uppershaft is journaled in movable boxes, the front one, h, of which iscapable of vertical movement in the head fz?. A spring, 7.-., pressesthejoulnalwith the upper feed-roll in a downward direction, the pressurebeing regulated by a screw, k. The skiving or feather-edging knife isseen atl. The cutting-edge of the knife is horizontal, while the surfaceof the feedroll and the plate y, upon which the sole rests, areinclined, to conform to the inclination to be cut upon the surface ofthe sole, and as they pinch the edge between thein they bear it in aninclined posi. tion against the knife-edge, causing the up per edge tobe chamfered or skived cil', as will be readily understood. Now, inother machines of this character where feed rols are used and a knife isto operate on or parallel to the edge, it is necessary to hold or guidethe edge by hand up to the surface against which it is to bear toregulate thc cut. I dispense with this necessity by applying the guidingor directing rod m. This rod extends down through two projections, a,from the head i. lts lower end is inclined, as seen in the drawings,down to arounding point. This point extends a little below the p lane ofthe lower edge of the top roll, so that it shall impinge against theupper surface of the sole, the sole being pinched between this point andthe surface of the plate y beneath as well as between the adjacentsurface of the two feed-rolls. A collar-plate, p, is fastened to the rodjust above the lower projection n, and a spring, q, bearing against thiscollar and the upper projection a, keeps the guide-rod down. To raise itto inse-rta sole, a lifter-lever, i, isjointed to the top ofthe bar, andthe collarplate is so applied that it can be raised or lowered andfastened in position to adjustthe distance of the point of the rod m tothe thickness of the sole being operated upon.

The operation ofthe machine is as follows: The sole heilig insertedandthe point of the rod m let down thereupon, the edge of the sole beingagainst the front side of the head 1', as the feed-wheels turn the points has a tendency to stop the sole, but the points on the feed-wheelscarry it on, and these teeth being between the point s and theguide-face t, they Iswing the sole m, and as the sole is fed the teethor the feed-wheels keep up their press- ,ure on the sole inside of thepoint s, and keep the edge of the sole against the surface t;

hence the sole cannot be fed out, but, will continue to be fed round itsedge so long as the feed-wheels are turned.

To 1 emove the sole when skived, the pointerrod is liftedwhen the teethwill feed the sole in astraight line until it is run out of the machine.

The spring q and the spring k allow the `guiding-point s and the upperfeed-roll to yield to the inequalities ot' the stock; but while themachine is in operation the knife cannot move, so that, however unequalin thickness the stock is, the edge of the sole is trimmed to a uniformthickness.

To adapt the machine to stock of different t thicknesses, and regulatethe thickness given to the edge of the sole correspondingly, the knifeand upper roll are so applied as to be movable togelher for the purposeof adjustment. 'l`he knife is txed between plates x x, the lower one ofwhich is fixed upon thev top ot' an adjusting-screw, u. A projection, e,extends from this plate under the journal-box h, so that when the knifeis raised by the screw u the boX h `and the upper feed-wheel are raisedwith it, and when the knife is lowered by the screw the spring k keepsthe box in` contact with the projection c, thus maintaining the k nifeand feed-roll in the same relative normal position, while the projectiondoes not prevent the roll from rising independently of the knife iorthevarying thickness ofthe sole.

ln pegging soles by hand it is customary to space oft' holes for theinsertion of the awl and peg; but such spacing is imperfectly effectedby hand. To adapt this'machine to such purpose, the teeth o on the lowerroll are arranged at the distance from the bearingsui-facet that thepegs are usually driven from the edge ot the sole. As the sole is fed,these teeth or points puncture holes parallel to or rqnidistant from theedge of the sole, which holes answer for the insertion of the points ofthe pegs. The lower roll may be made capable of falling, to allow theintroduction of the sole between the rolls, and one or both rolls may beremovable for replacement by othersof varying inclination, to alter theinclination of the chamfering eut. A friction-roll may also be used,instead ot' the stationary surl'aeeplate.

I will here remark that though 1 have describedthe adaptation of theguidingrod m to a machine for feather-edging soles, it may be applied toother machines in which stock is to be trimmed or operated upon in alineor lines equidistant from the edge of such stoi k or from the edge of apattern or plate upon which such stock may be fixed-as, for instance,channeling or grooving'knives may be employed instead ot' or inconnection with the skiving-knife; or an upright knifemay be txedto thehead fi, or otherwise so arranged as to cut or form the shape of thesole from a pattern, which pattern is held against the guiding surface tby the rodm. These and various other modifications may be embcdii d uponthe machine without departing from the spirit of that part ot' myinvention relating to the employment ot' the guiding-rod m.

l. In connection with feeding and cutting mechanism and a guidingsurface, the employment of a directing rod or point to keep the stockagainst the guiding-surface.

2. The construction of the lower feed-roll with dinking-points soarranged as to puncture and space the holes for the peg-points,substantially as described. f

3. The arrangementof the mechanism by which, while the knife inoperating has a fixed relation to the surface of the lower feed-rolt,the directing-rod and upper feed-roll yield to the inequalities of thestock.

At. The construction by which the knife and upper feed-roll are raised,lowered, and fixed in position together, substantially as set forth.

5. Combining a horizontal skiving-knife with inclined-surfacefeed-rolls, in the manner and for the purpose substantially asset forthLOUIS GODDU.
